Wood, xylem (ksylos in Greek means wood) is the name for a compound heterogeneous plant tissue which is created in the process of vascular plants growth. Depending on the fundamental directions of its anatomy (longitudinal radial, longitudinal tangential and transverse) it manifests various mechanical characteristics. As an organic renewable resource, it has been accompanying people on everyday basis since prehistoric times. Civilization development has also promoted wood utilization as a resource essential for distinct areas or developing industry. It has been currently estimated that wood is used in over 10 thousand applications32. The versatility and in numerous cases even irrevocability of wood usage makes it a highly desirable resource. Its temporary shortage causes many conflicts between the sellers and the buyers as well as the recipients themselves.
This paper deals with the determination of end user attitudes towards different ways of wood utilisation. The preferences of consumers for the selected wood properties in comparison with substitute materials were assessed for the area of joinery products and furniture used in households. The survey was carried out using a questionnaire survey of the selected sample in the Slovak Republic and in Poland. The research identified competitive properties of wood and compared preferences of consumers for wood in both countries.
Mangroves are various types of trees up to medium height and shrubs that grow in saline coastal sediment habitats in the tropics and subtropics mainly between latitudes 25° N and 25° S. Mangrove ecosystems represent natural capital capable of producing a wide range of goods and services for coastal environments and communities and society as a whole. Some of these outputs, such as timber, are freely exchanged in formal markets. Value is determined in these markets through exchange and quantified in terms of price. Particularly the mangroves of Rhizophoraceae have so many ecological importances. Breeding and nursery grounds for a number of marine organisms including the commercially important shrimp crab and fish species. Mangrove trees are also used for house building, furniture, transmission as well as telephone poles and certain household items. Mangrove trees have been the source of firewood in India since ancient time. Because of the high specific gravity of rhizophoraceous wood, the species of Rhizophora, Kandelia, Ceriops and Bruguiera are preferred for firewood.
